DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact container suitable for filling and containing a foundation.
While reducing the size and thickness of the container itself,
It is intended to maintain high airtightness for a long time. Hereinafter, such a container is housed in the main body of the compact container, it is also possible to use as a refill container to be loaded,
Here, a case where the present invention is applied to a refill container will be described.

[0002]

2. Description of the Related Art Among foundations, those having a particularly high volatility and those containing a relatively large amount of water are provided in a container with a lid which is separate from the refill container body in order to avoid evaporation of the volatile components and water. It is usually filled and stored, and in order to enhance the airtightness of the container, it consists of a plurality of parts with a sealing member such as rubber packing or foam packing incorporated between the container body and the lid. Have been.

[0003]

The refill container of this type is usually housed and loaded in a compact container, whereas a container composed of a plurality of parts is large in size. Is inevitable, and with this,
There is a problem that the size of the compact increases. Also,
Despite the fact that the refill container frequently opens and closes the lid, the packing may be damaged before the contents are used up. In that case, it is difficult to maintain the quality of the contents.

[0004] It is an object of the present invention to propose a novel compact container which can reduce the size and thickness of the container itself with a one-part structure and can maintain high airtightness for a long period of time.

[0005]

SUMMARY OF THE INVENTION The present invention is a compact container comprising a container body for filling and containing contents, and a lid which fits into the container body and separates the inside and outside of the container. The mating surface with the body is provided with an airtight portion integrally formed with the body, the airtight portion being formed on at least one of the container body and the lid, an annular wall formed on at least one of the container body and the lid, and the entirety of the annular wall formed from the other. , The container body and the lid body are provided with engaging projections that suppress opening of the lid body against the will by engaging with each other.

In the compact container having the above structure, it is preferable that the container body and the lid are integrally connected by a connecting means consisting of a plate-shaped main hinge and a spring hinge sandwiching the main hinge from both sides. The container may be used as a refill container housed and loaded in the body of the compact container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 shows the appearance of the compact container according to the present invention with the lid open, FIG. 2 shows the side surface with the lid closed, and FIGS. 3 (a) and 3 (b) show the lid. FIG. 2 shows planes in a state where is opened. In the figure, reference numeral 1 denotes a container body for filling and storing a foundation, 2 denotes a lid that fits into the container body 1 and separates the inside and the outside of the container, and the lid 2 and the container body 1 are connected by a connecting means 3. They are integrally connected.

The connecting means 3 comprises a plate-shaped main hinge 3a and a spring hinge 3b sandwiching the main hinge 3a from both sides, and the lid 2 is mainly opened and closed by the main hinge 3a, as shown in FIG. The simple operation of the lid 2 can be guided from the closed state to the first open state (position A in the figure) and the second open state (position B in the figure) by the elastic force of the spring hinge 3b. I have. In other words, the first open state and the second open state are the stable positions of the lid 2.

Reference numeral 4 denotes an airtight portion integrally formed on the mating surface of the container body 1 and the lid 2 respectively. As shown in FIG. 5, the airtight portion 4 has a cross section of the container.
Inner / outer double annular wall 4 forming annular space K in container body 1
a, 4b, and sandwiching walls 4c, 4d which enter the annular space K from the lid 2 and sandwich the annular wall 4b from both sides in the entire area (entire circumference). In this example, the annular walls 4a and 4b are provided on the container body 1 and the holding walls 4c and 4c.
Although d is shown as an example integrally formed on the lid 2, the opposite is true, that is, even if the annular walls 4a and 4b are integrally formed on the lid 2 and the holding walls 4c and 4d are integrally formed on the container body 1, respectively. Good. Here, as shown in FIG. 5, the annular walls 4a and 4b do not necessarily have to be double, and for example, the tubular wall 4a may be provided locally.

Reference numerals 5a and 5b denote annular walls 4 of the container body 1.
a are engagement projections (local ones) shown in an example of an annular shape formed on the outer peripheral surface of a and the inner peripheral surface of the peripheral wall of the lid 2, and the engagement projections 5a and 5b are containers. Body 1
When they are closed with the lid 2, they have a role of engaging with each other to suppress opening of the lid 2 against the will.

[0011] The container having the above-mentioned structure can be made of a single material, all of which are integrally molded. The number of parts is small, the size can be reduced and the thickness can be reduced. Extremely high. Further, the airtight portion 4 and the engagement protrusion 5
Since a and 5b are independently provided in a single material, it is only necessary that each part retains its function, and the management in the container manufacturing process and the like can be simplified.

FIG. 6 shows a state where the container according to the present invention is housed in a compact container as a refill container. In the figure, reference numeral 6 denotes a compact container. Since such a refill container can be reduced in size and thickness as described above, the size of the compact container 6 that accommodates the refill container can be minimized.

The container of the present invention can be integrally molded by injection molding or the like of a thermoplastic resin such as polypropylene or polyethylene. However, the present invention is not limited to such a resin. Any material can be used as long as it can enhance the sealing performance in the hermetic portion 4 disposed between the members, and various materials can be used.

[0014]

According to the present invention, since the compact container can be constituted by a single member, the size of the container itself can be reduced in size and thickness, and when used as a refill container, the size of the compact container can be reduced. Can be kept to the minimum necessary.In addition, since an airtight part that is integrally formed is interposed between the container body and the lid, the airtightness is extremely high, and the airtightness is maintained for a long time. Is done.
